3 Secrets to Keep Your Ducts Clean Forever


When was the last time you had your air ducts cleaned? If you are like most people, you’ve never had them cleaned. Because they are out of sight, they are also often out of mind, and many people just assume that they function perfectly well, no matter how often you use your HVAC system or how often they have been cleaned.

The truth is, however, that in just a few years, layers of dust and other particles carried by the air can start to line and then clog up your ducts. And not only will the air be carrying all of these particles back out into your rooms, they also make it much more difficult for your HVAC system to function properly.

If you want cleaner ducts, so you do not have to pay for as frequent air duct cleanings, here’s what you can do to keep your ducts clean forever (or at least as long as possible):

  • Use MERV 8 filters
  • Install Air scrubbers or UV light 
  • Make sure ducts are sealed

Secret #1  USE MERV 8 Air Filters 

All air filters are given a rating, using the Minimum Efficiency Rating Value. This is a standard used across the entire industry that allows consumers to see how effective and efficient the filters are at capturing and holding on to dust. In general, the higher the rating, the better the filter is, with a rating scale from one, being the least efficient, and twenty, being the most efficient. These numbers should tell you which air filters you should be buying for your systems.

Why do filters help keep your ducts clean? Your ducts are used to push air from your air conditioner or furnace, into the rooms of your home. If you did not have a filter in these systems, all of the dust and pollen in your air (and outside of your home), would simply be sucked into the system, cooled or heated, and then pushed back into your rooms. Some of that dust and pollen would stick the sides of your ducts, creating build up that only catches more particles and eventually clogs your ducts.

When you have an efficient air filter, however, the system will trap much of those particles long before they ever get to your ducts, which keeps those ducts clean. They also ensure that the air that you breathe in your home or office is much cleaner and fresher. A great filter will prevent pollutants, pollen, dust, and other irritating particles from being cycled back into your rooms.

A filter with a MERV 8 is considered to be one of the better filters. It is usually sufficient for keeping most ducts clean in most HVAC systems. Keep in mind that while higher ratings are more efficient, more efficient filters can adversely affect the performance of your HVAC system.

Secret #2 buy a air scrubber

There are lots of different systems that claim to purify the air in your HVAC system. While purifying the air in the system will definitely help to keep your ducts clean, you actually have to use a system that cleans the air and doesn’t just claim to clean the air. This is where a UV light Air Scrubber comes in. It should be mentioned that while you do already have a filter in the system, most filters are not capable of capturing and holding on to germs, which can be just as bad in your ducts as dust is.

An Air Scrubber, on the other hand, is ideal for cleaning those germs out of the air, so that your ducts stay cleaner. Having bacteria in the air is a huge problem. There are plenty of airborne illnesses that can travel to person to person, even if those two people never touch the same doorknob or hard surface in the home. The germs are released into the air and then they are circulated by the HVAC system, passing freely through the filter. An Air Scrubber uses UV light to kill both airborne and surface germs, for a much healthier HVAC system.

Just like dust, germs can build up and fester in your ducts. While you might not be able to see them, the germs living there will be redistributed throughout the rooms of your commercial building or home, if there is no system in place to kill them. Using a UV light solution is one of the best ways to kill them and keep your ducts clean.

Secret #3 Make sure your ducts have a good seal

If your ducts do not have a good seal, just as much air will leak into them as air leaks out of them. When ducts have an inadequate seal, the biggest concern is that the cooled or heated air will leak into the walls of a building, without ever reaching the rooms. This makes it much more expensive to heat or cool a location, but it also allows dust and other particles, especially from insulation, get into the ducts. Over time, particles will start to build up along the walls of the ducts and then they will become completely clogged.

“Five stars--could not be happier!  Josh and Kyle were very professional, provided several options to improve performance of HVAC, no pressure or time constraints, worked efficiently, were able to explain in clear terms what they found, including when items were performing in fine fashion and nothing needed to be done.  Thanks for a happy camper”


“Service was outstanding from the time of arrival which you could track arrival time live on a website link they send you so you know when they will arrive. Technical knowledge was very high, quick and efficient Kyle and his partner both handled the install of a Sensi Predict as if it was a walk in the park. I highly recommend Kyle from Nice Heating & Air for all HVAC issues and for new installs, him and his team are an amazing company and will think of them first if any issues arise in the future for sure....”

“Highly recommend Nice Home Services for your HVAC needs. Have been member of their annual maintenance plan for three years now and been extremely pleased with their approach to business. They are professional, knowledgeable, and relatable. The service specialists take their time to fully diagnose the issue and explain the situation in a way that is easy to understand. Never had an instance where they try to push product and instead look for ways to recommend how to save you money. Need anything done on your home's HVAC, call the folks at Nice Home Services and know you're making the right choice.”

Richard Nowinski.

“Dionte and his helper (Josh) did a superb job with the installation. The result is both functional and as cosmetically pleasing as the ideal water heater installation can be. They were VERY careful moving the old one out and the new one in so as to assure no damage was initiated neither to the heater nor to our dwelling. He explained his intended design prior to execution and executed it flawlessly. This was followed by a comprehensive explanation of the functional options available through the control panel and Ipad app. Cleanup at conclusion of the install was appropriate and comprehensive. This team represented both Nice Heating and Rheem VERY positively!”

Kimberly Mason.

Would recommend and will be using them again in the future. ”
